About Our Club

The Manhattan, Kansas Amateur Radio Society (MAARS) was formed on July 7, 1976. The purpose of the club is to advance amateur radio in the Manhattan area. Since the beginning, the club has been active in different aspects of amateur radio, packet radio, satellites, community activities, ARRL Field Day, and amateur radio classes. Also, many club members have been very involved through the years with emergency communications and storm spotting. The club operates under the authority and guidelines of our Constitution.

  • Echo Link

    from Dave, KDØAZG

    I have made repairs to the radio and PA for the Echo link server. I have made some changes on how to access nodes, should you want to DTMF a Echo link node. You must enter 1*, then your Node number. We were having trouble with other DTMF codes being broadcast on the KLINK that made a connection on our Echo link server. By adding in the 1*, this should help resolve this issue.

    Remember, ECHO link is a no-tone operation, so should you connect with someone calling CQ via ECHO LINK, please disengage your tone. Enjoy.


    Meetings are now in the Manhattan Public Library, 629 Poyntz Ave., on the usual schedule of second Fridays. Check Upcoming Events below to confirm details for the next meeting.

    Located 1.5 miles south of Manhattan, Kansas, the MAARS repeater is at the KSDB site near K-177. The controller is an S-Com 7K. The repeater runs 10 watts output to a commercial antenna at 110 feet. Coverage as far east as Topeka and as far west as Abilene is common. The input frequency is 147.855 MHz, and the output frequency is 147.255 MHz. The repeater callsign is KSØMAN. The repeater is an open repeater, and may be accessed by any properly-licensed amateur.

    Users of the KSØMAN repeater should be familiar with the autopatch procedures and other guidelines.

    Jan. 10, 2020: From Ryan Benteman, ADØTZ: I thought I'd give an update on the repeater upgrade project for the 147.255 KSØMAN machine.

    I'm pleased to say that the repeater committee has been able to locate and purchase a matched pair of Motorola Quantar 125-watt repeaters, as well as an additional duplexer.

    Mike and Suzanne Asbury spent a day this past week taking the equipment down to Mobile Radio in Great Bend, a Motorola shop, to have them checked out and aligned. The shop gave them a clean bill of health, said they were in great shape, got them programmed and set up on our frequencies.

    We hope to have the new machine up and running in the coming weeks, as time allows. Keep in mind we all have to schedule time off work from our normal jobs to be able to do anything at the repeater site, and we've got a few things we'd like to do while we're there.

    With the new equipment, we now have two identical, commercial-grade repeaters, along with another duplexer to match with the second repeater. This additional equipment gives us the ability to do a couple of things. First, it is a plug-and-play backup machine, that gives us the ability to take one machine offline for maintenance or repairs, and still have a fully-functioning repeater. Second, it gives the ability to locate the second machine at a different site, if we'd like to try out a second repeater location.

    I've had multiple club members ask me to just fix the damn repeater. Well, guys, we're moving forward with the upgrade by bringing in newer, currently-supported equipment that should last well into the future. Now, with newer equipment and matching backups, we are in good shape into the foreseeable future.

    The next step after installation of the new 147.255 machines is to look at locating our APRS station on a higher antenna for a larger coverage area, and move the 442.000 Fusion machine for better coverage over the whole town.

    Once again, thanks for your patience.

    Dec. 22, 2019: From Ryan Benteman, ADØTZ: The KSØMAN repeater, 147.255+, is functioning well with an 88.5 tone. Without a tone, it won't key.

    This is a large footprint repeater, with a coverage of roughly 60 mi radius of the surrounding area.

    Lots of people leave radios listening to the repeater at all times. Please be courteous with your conversations, and even if you don't hear any activity on it, don't be afraid to key up and give a call out. Dave Mills, KDØAZG, is gracious enough to host an EchoLink node for the repeater, so if you hear a unfamiliar call on there, it very well may be an EchoLink station. Allow them a little longer on the TX times, due to the delay though the Internet system linking them. Or, if you'd like to check in while traveling, it's a great way.

    You may also hear unfamiliar calls on the radio. Go ahead and answer them. They won't bite. Even if you don't have long, a quick answer to let them know it isn't a dead repeater is welcome. I know when I'm traveling, if I key up a repeater its always nice to have someone come back, even if it's just a quick check.

    There does seem to be an intermittent problem where some radios won't key the repeater at some times. We're not entirely sure why this is. We don't have a special module in the radio that doesn't allow certain radios, it's just what is going on right now, and we will live with it.

    We have sourced a 125w Motorola Quantar VHF machine and suitable controller, to move forward with upgrading our 2m repeater. These are commercial grade, public safety radio repeaters that are designed to work in RF noisy sites.

    It still has to be shipped to us, gone through, given a clean bill of health, controller installed, repeater programmed and aligned, and then installed in the shack. We're planning for a February 1 operational date, but as with everything, nothing worth having is acquired easily.

    Thanks and Merry Christmas,

    Ryan Benteman, ADØTZ

    • Join us for breakfast with a side of ham! It is always fun to see and hear what friends in the amateur radio community are working on. If you have questions about anything ham radio related, we always have informal breakout sessions in the restaurant, or in the parking lot after breakfast.

      Don't be late, and please bring all your show and tell projects. It is a great way to inspire hams in exploring different aspects of the arts and science of amateur radio.

      Thanks to everyone who supports our club, meetings and nets. It wouldn't be much of an organization and net without You.
